            <p>
              Here you can learn about the structure and applications of Pytorch3D from
              examples which are in the form of ipython notebooks.
            </p>
            <h3> Run interactively </h3>
            <p>
              At the top of each example you can find a button named <strong>"Open in Colab"</strong> which will open the notebook in <a href="https://colab.research.google.com/notebooks/intro.ipynb"> Google Colaboratory </a> where you can run the code directly in the browser with access to GPU support e.g.
            </p>
           <img align="center" src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"/>
           <p> You can modify the code and experiment with varying different settings.
        Remember to install pytorch, torchvision, fvcore and pytorch3d in the first cell of the colab notebook by running: </p>
            <MarkdownBlock>{bash`!pip install torch torchvision
!pip install 'git+https://github.com/facebookresearch/pytorch3d.git'`}</MarkdownBlock>
           <h3> Run locally </h3>
           <p> There is also a button to download the notebook and source code to run it locally. </p>
          </div>
        </Container>
      </div>
